With Lexus' ES and GS executive saloons being similarly sized, even our spies were a bit more puzzled as to which it exactly was they've seen rolling around Germany in full camouflage. Considering the fact that this particular vehicle was being benchmarked against a Mercedes E-Class, we initially thought of the next-gen ES.

Several rumors suggest that the current GS will be the last model of its kind – with development for the upcoming model supposedly being canceled. Since the GS won't be having a successor, this may well be a Lexus ES. If not that, maybe Lexus will introduce a new model altogether?

Quite interesting as well on this test mule is the apparent absense of a 'spindle grill' which defines the front end of every Lexus model.

Considering the heavy camo and scarce details, there’s not much to point out other than the fact that this mule is a hybrid (a round yellow sticker on the rear glass supposedly hinting to such).

As it turns out, this test mule the next-gen Toyota Crown. Hence the absence of a spindle grill.
